  • Patent number: 7630979
    Abstract: An information retrieval terminal provides keywords to an information retrieval device and instructs it to retrieve by using such keywords. The information retrieval terminal includes an information collector for collecting screen information, image information, and voice information around the information retrieval terminal and for obtaining text information from the collected information. A keyword-candidate extracting unit extracts a word related to a retrieval word input by a retriever from the text information obtained by the information collector, and sets the extracted word to be a keyword candidate. A retrieval instructing unit gives an instruction to retrieve by using the retrieval word and the keyword candidate set by the keyword-candidate extracting unit as keywords.

  • Patent number: 7477978
    Abstract: A device adapted to automatically control the effective output of a vehicle control system/component that, for example, automatically applies braking and/or steering control, in response to tire contact with a rumble strip. The device includes a processor configured to receive a first signal indicative of contact of a vehicle tire with a rumble strip. The processor also includes logic to determine that at least one vehicle tire is in contact with a rumble strip based at least on the first signal. If the processor has received the first signal and has determined that the at least one vehicle tire is in contact with the rumble strip, the processor then issues a command to control the effective output of at least one of a vehicle control component or a vehicle control system. For example, an automatically applied braking force may be reduced to ½ its normal applied force.

  • Publication number: 20080043243
    Abstract: There is provided a system always capable of detecting AE/ultrasound received by an FBG, even when the FBG receives a change in temperature or strain and the Bragg wavelength is fluctuated. In the AE/ultrasound detection system, the reflected light from the FBG is caused to enter a Fabry-Perot filter having an FSR equal to or greater than the reflection wavelength band of the FBG. A change in the intensity of the transmitted light corresponds to the AE/ultrasound received by the FBG. Alternatively, the reflected light from FBG is caused to enter two Fabry-Perot filters having an FSR equal to or greater than the reflection wavelength band of the FBG and having the filter-transmittance peak wavelengths different from each other by FSR/4. The intensity of the transmitted light from each of the two Fabry-Perot filters is converted into a voltage signal, and the individual signals are subjected to addition and subtraction processes.

  • Publication number: 20070225914
    Abstract: An a lane departure prevention system is described having a position detector for detecting positional information of a vehicle with respect to a lane of travel. A determining unit is included for comparing the positional information with a first threshold value indicating a predetermined positional relation with respect to the lane of travel, and for determining a tendency of the vehicle to depart from the lane of travel on the basis of a comparison result. At least one control is selectively adjusted when the determining unit determines that the vehicle is tending to depart from the lane of travel. The at least one control is selectively delayed or selectively reduced as a result of a proximate predetermined physical object.
